nvAnnniE cor and exact descri or the invention, which will enab e H lowing is o, iull, clear, tion turns to make and use the same.

This invention relates to a process for the production of fresco-paintings and colored "hcnprooi architectural ornaments.

t process is known by which glass mosrc' produced by burning in p eces of int a high tem ereture on cement This process as the disadvantage mossics leevin, the oven or furnace 1 only a slight egree of strength or y end must be stored for a considerinne before they can be used, in order t renewed bin ing of the cement may e piece; they nevertheless, remain very rilnnd es, moreover, the requirement glass pieces shall be fast cemented in necessitates s. high burning temperature, the employment of the process for decorative purposes is limited.

iicw, hsve discovered a new process by which not only are the above described deobviated but also the manufacture is simplified end an artistic ornamentation and eifect rendered possible. To this end in lieu of employing ieces of glass I make use of ceramic and g ass colors whereby I am skilled in the art to which it upperenabled to prepare fresco-paintings; also instead of a concrete mass of cement and admixtures, Intilize acement mixture in which flux-like addmons, for example, feldspar, granite basalt, o'und glscccnd similar naturally or arti ciall ging 'substences'can'be made use. o.

admixtures. The. ainting may be apple to the erticles betore setting but generally preferable to apply it thereertcr as the erticles can be more conveniently handled. The goods are then introduced into an oven or furnace end only require burning at a moderate heat. The relatively easily fusible substances ceke with the cement and the whole mess combines with the colors applied to it so as to term a solid mass. As, moreover, the main part or body of the article is quite porous, it absorbs more or less of the colors and after the firing the design will have a less glittering appearance than it otherwise would. It is true that the main body or base does not absorb the colors e ually but usually a sufficient amount of t e surface colors are absorbed to effect the result stated.- Therough cur face ofitself aids in producing this effect and where the colors are not so fully ebsorbed relieves such parts from the glittering appearance that would otherwise be produced. lhey are distinguished from ordinary glazed clay ioods by their softe up earance and the re uced amount of light re ected. They differ from these also advantageously by the hardening qualities of the raw mass. The articles or goods oi? cement and admixtures can be thin and of complicated shape without any risk oi frecture during the painting process. Further more, they ossess the extreme advantage of not shrin ring under heat or in any event of exhibiting practically no shrinkage as compared with clay goods. There are, therefore, no rejections due tounoqual contraction or warping, no. splitting occurs, andfitted ieces exactly fit after firing. it, therefore, ecomes unnecessary to trim or finish the goods after the firing or burning OPGIMJOII.

It will be obvious that sand and quartz canbeadmixed with the fusible admixtures to thecement without in any way modifying the process herein-described.
